Market frenzy leaves investors cautious

Even seasoned market investors are starting to pull away from the frenzy surrounding China's stock market.

Zhao Qiuhai has been a freelance trader for 10 years and lives in Shanghai's Jing'an district. In March, he became so concerned about the A-share market, he decided to sell 80 percent of his stocks even as the bull run continued.

"I always tell myself that the stock market is risky," Zhao, 35, said. "It's certainly more risky for retail investors like me."
